Answer:
[tex] \huge \: t = \frac{13}{2} [/tex]
Step-by-step explanation:
[tex]10t - 5 = 60[/tex]
Using the addition property add 5 to both sides of the equation
That's
[tex]10t - 5 + 5 = 60 + 5 \\ 10t = 65[/tex]
Divide both sides by 10
[tex] \frac{10t}{10} = \frac{65}{10} \\ t = \frac{65}{10} [/tex]
Reduce the fraction with 5
We have the final answer as
[tex]t = \frac{13}{2} \\ [/tex]
Hope this helps you
Answer:
t = 6.5
Step-by-step explanation:
10t - 5 = 60
Add 5 to each side
10t -5+5 = 60+5
10 t = 65
Divide each side by 10
10t/10 = 65/10
t = 6.5
prove the two triangles are similar

Answer:
the sides are congruent.

what is the slope of the line in the graph?
Answer:
It is one. I believe, sorry if i'm wrong.
Step-by-step explanation:
Answer:
y= x +1
Step-by-step explanation:
You could use the slope formula y2-y1/x2-x1, what I did was I took the og equation y=x and I noticed it was vertically shifted by 1. Thus, y=x+1
Gi dont understand how to find Which ordered pair is a solution of the equation? y=8x+3
Answer:
(1, 11 ) is a solution
Step-by-step explanation:
To obtain a solution, choose any value of x, substitute into the equation and evaluate for y, that is
choose x = 1, then
y = 8(1) + 3 = 8 + 3 = 11
Thus (1, 11 ) is a solution
choose x = - 2 , then
y = 8(- 2) + 3 = - 16 + 3 = - 13
Thus (- 2, - 13 ) is also a solution
Lets go over the solutions.
Let's start with (1, 11). After substituting x = 1 and y = 11, it results in the equation 11 = 11, which is a true statement. Hence, this is one solution.
Now, let's look at (-1 -5). After substituting x = -1 and y = -5, it results in the equation -5 = -5, which is also a true statement. So, this being said, (-1, -5) would also be a solution.
Hence, our two solutions are:
Both [tex](1, 11)[/tex] and [tex](-1, -5)[/tex].

4x+13x=119 what does x=?
x=7
Answer:
x = 7
Step-by-step explanation:
Given
4x + 13x = 119 ( collect like terms on left side )

In response to a gss question in 2006 about the number of hours spent per day watching television, the responses by the fifteen subjects who identified themselves as Buddhist were 0, 0, 0, 1, 1, 1, 2, 2, 2, 2, 2, 3, 4, 4, and 5. For these fifteen subjects, the mean number of hours spent per day watching television is 1.93 hours. What is the standard error of this mean estimate?
Answer:
Standard error = 0.4
Step-by-step explanation:
Step 1
We find the Standard Deviation
The formula = √(x - mean)/n - 1
n = 15
Mean = 1.93 hours
= √(0- 1.93)² + (0-1.93)² +(0- 1.93)²+( 0- 1.93)²+ (1- 1.93)² + (1- 1.93)² +(1 - 1.93)² +(2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + ( 2 - 1.93)² +(4 - 1.93)² +(4 - 1.93)² + (5 - 1.93)²/15 - 1
= √(3.737777776 + 3.737777776 + 3.737777776 + 0.871111111 +0.871111111 + 0.871111111 + 0.004444444445+ 0.004444444445 + 0.004444444445 + 0.004444444445 + 0.004444444445 + 1.137777778 + 4.271111112 + 4.271111112 + 9.404444446)/15 - 1
= √2.352380952
= 1.533747356
Step 2
We find the standard error
The formula = Standard Deviation/√n
Standard deviation = 1.533747356
n = 15
= 1.533747356/√15
= 1.533747356 /3.87298334621
= 0.39601186447
Approximately = 0.4
Therefore, the standard error is 0.4

What is the number a solution of 6x-3>10?
Answer:
x > 1.167 (rounded to the nearest thousandth)
Step-by-step explanation:
Original Equation:
6x - 3 > 10
Add 3 to both sides
6x > 7
Divide both sides by 6
x > 1.1666666. . .

If 6 pounds of blueberries costs $16.50, is $1 for 2.75 pounds of blueberries true?
Step-by-step explanation:
Hmm I'm not sure but (no) I think
6 pounds = $16.50
1 pound = $16.50 ÷ 6
=$2.75
$16.50 = 6 pounds
$1 = 6 ÷ $16.50 = 4/11 pounds (0.36363636......)

how many solutions does this equation have?
7(2+5x)=3x+14
Answer:
none
Step-by-step explanation:
If you use the distributive property, you get 14 + 35x = 3x + 14. Then, subtract 3x from both sides to get 14+32x=14. Subtract 14 from both sides to get 32x= 0. These aren't equivalent, so there are no real solutions. Hope this helps!

What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given: The system of linear equations as 7(2+5x)=3x+14
simplifying the equation we get
7(2+5x)=3x+14
14+35x=3x+14

Answer:
The area of B is 8 cm²
Step-by-step explanation:
From the diagram, we can tell that the scale factor is 2 because the length of A is 6 cm and the length of B is 12 cm so the scale factor is 2. Since diagram A's area is 4 cm², all we need to do is multiply the diagram A's area by 2. That gives diagram B's area which is 8 cm²

I am going to keep this simple and I am going to help people out who need points. What is 4 x 9?
Answer:
36
Step-by-step explanation:
1. The line through A and B has a slope = _____ and y-intercept = _____
2. Write an equation for this line. ________
Answer:
1. slope= 1/2; y intercept=3
2. y= 1/2x+3
Step-by-step explanation:
The slope is equal to the y value of b minus the y value of a OVER the x value of b minus the x value of b. This simplifies to 1/2.
If the slope is 1/2, you can see that for every 1 that the line rises, its x value increases by 2. Since you know the when the x value is 2, the y value is 4, decreasing the x value by 2 (making it 0) would make the y value 3.

Answer
Step-by-step explanation:
The answer would be y=-x-3. 3x+3y=-9 is in standard form and you want it to be in y=mx=b form (slope-int) so subtract 3x by both sides. Now, you have 3y=-3x-9. Divide 3 to both sides, now you will get y=-x-3.
